Description
BACKGROUND

Computer systems usually have a graphical user interface that enables a user to use a mouse to “click” or “double click” an icon on a display to view the contents of that icon. For example, if the icon represents a folder, double clicking on the icon will cause a new window to be shown on the display containing the constituent elements of the selected folder. The constituent elements may comprise additional folders and/or files. Searching the multiple folders may involve a great deal of clicking which can be cumbersome to the user.

DETAILED DESCRIPTION

The following discussion is directed to various embodiments of the invention. Although one or more of these embodiments may be preferred, the embodiments disclosed should not be interpreted, or otherwise used, as limiting the scope of the disclosure, including the claims. In addition, one skilled in the art will understand that the following description has broad application, and the discussion of any embodiment is meant only to be exemplary of that embodiment, and not intended to intimate that the scope of the disclosure, including the claims, is limited to that embodiment.

FIG. 1 shows a system 10 in accordance with various embodiments. As shown in the illustrative embodiment of FIG. 1, system 10 comprises logic which preferably comprises a processor 12 coupled to a computer-readable storage medium (CRSM) 14. The system 10 also comprises an input device 18 (e.g., a mouse, trackball, keyboard, etc.) and a touch-sensitive display 20. The storage 14 comprises volatile storage (e.g., random access memory), non-volatile storage (e.g., hard disk drive, read-only memory, compact disc read only memory, Flash storage, etc.), or combinations thereof. Storage 14 preferably contains software 16 that is executable by processor 12 and, that when executed, causes the processor to perform some or all of the functionality described herein.

The touch-sensitive display 20 comprises any suitable type of touch-sensitive display such as a desktop flat panel monitor or a handheld display unit. In some embodiments, the entire system 10 is a hand-held unit, while in other embodiments, system 10 is not hand-held (e.g., a desktop system, notebook computer, etc.). Any of a variety of technologies can be used to detect a user's finger(s) on the display (e.g., capacitive, camera-based, etc.).

FIG. 2 illustrates a screen shot of a graphical user interface (GUI) 30 displayable on touch sensitive display 20. The GUI 30 comprises one more object icons 32. Each such object icon is a graphical symbol that represents and is associated with an object (i.e., a data structure). The data structure may comprise a folder, a directory, a file, etc. As a folder, for example, the object icon 32 permits a user to view the contents of such a folder. The contents of the folder may comprise additional folders, files, or combinations of folders and files. As noted above, using a mouse a user can click an object icon 32 representing the folder to view a list of the constituent elements (files, folders, etc.) of that folder.

In accordance with various embodiments, however, a user can select and view the contents of an object icon using a finger-based gesture on the touch sensitive display 20. FIGS. 3A-5 illustrate one exemplary gesture to view the contents of a displayed object icon. In the following explanation, the object being selected is referred to as a “base” or “first” object icon to distinguish it from the constituent elements, which themselves may be additional object icons, that are displayed when the base object icon is selected. Thus, a base object icon is selected and additional object icons are displayed as well that represent the constituent elements of the selected object icons. The use of the adjective “base” or “first” should not be construed as imparting any particular meaning to the associated object icon. One of the additional object icons itself can be selected to view its constituent elements and, at that point, the additional object icon being selected may be referred to as a “base” or “first” object icon. Thus, the object icons can be viewed in a nested fashion and base/first simply refers to the icon being selected.

FIG. 3A illustrates a user placing two fingers on a base object icon 32 to be selected. The fingers the user uses may be on the left and right hands as shown or may be on the same hand (e.g., thumb and forefinger). The user then moves the fingers apart in generally opposing directions. The direction in which the fingers move apart can be any direction. Arrows 36 illustrate one suitable pair of directions for movement of the fingers along an axis 40. The axis 40 can be oriented differently from that shown. For example, the axis 40 along which the fingers move apart can be horizontal, vertical, or at any other desired orientation.

The fingers can move apart in exactly or approximately opposing directions. FIG. 3B illustrates one arrow 36 originating from a point at which the base object icon is located. The axis 40 is shown coinciding with the arrow 36. The opposing arrow 36 (not shown in FIG. 3B) is within an angle A1 of the axis 40. Angle A1 is in the range of 0 to 10 degrees in accordance with at least some embodiments.

FIG. 4 illustrates the user's fingers beginning to move apart. As is shown, the object icons associated with the selected base object icon begin to appear (be rendered) on GUI 30. The object icons associated with the selected base object icon 32 are indicated by reference number 44. The size of the additional object icons 44 is a function of the distance between where the user's fingers touch the display 20. In some embodiments, the closer the fingers are together, the smaller will be the size of the additional object icons; the farther apart the fingers are, the larger will be the size of the additional object icons.

FIG. 5 illustrates that the user's fingers are farther apart than in FIG. 4. Accordingly, the size of the additional object icons 44 are bigger than in FIG. 4.

In addition to rendering the object icons associated with a selected base object icons, the system also renders arrows 46 from the selected base object icon to each of the additional object icons. Arrows 46 clarify to the user the association of object icons 44 to their base object icon 32.

As shown in FIGS. 4 and 5, the additional object icons 44 are shown in a generally circular pattern centered about the selected base object icon. Patterns other than circular can be used as well.

FIG. 6 illustrates another gesture in which a user uses a single finger to touch one of the additional object icons 44 and moves the finger generally along the circular pattern in a generally curved motion. As a result, the pattern of additional object icons is animated to thereby make the pattern appear to spin about a central point coinciding with the base object icon. The pattern can be made to spin in either direction—clockwise or counterclockwise—depending on which direction the user moves his or her finger. The pattern can spin indefinitely until stopped by the user touching the pattern, or for a predetermined period of time. Once the processor causes the pattern to stop spinning, the processor can cause the pattern to begin spinning in the opposite direction if the user moves his finger in such direction.

FIG. 7 illustrates a user selecting one of the additional object icons by double touching the touch sensitive display in rapid succession (e.g., two touches within two seconds). This gesture is akin to a user double clicking on the icon with a mouse. As a result, the constituent elements of the selected object icon are shown. An example is shown in FIG. 8 in which various audio files 50 are listed which were associated with the object icon selected in FIG. 7.

FIG. 9 illustrates a method in accordance with various embodiments. The method is performed in some embodiments by the processor 12 executing software 16 (FIG. 1). At 60, the method comprises detecting two fingers touching (i.e., selecting) a first object icon on a touch sensitive display and moving apart in generally opposing directions. At 62, the method further comprises, in response to the detection of the finger movement from action 60, causing additional object icons to appear on the display. Each such additional object icons represent a constituent element of the first object icon selected at 60. At 64, arrows 46 are also rendered pointing from the first object icon to each of the additional object icons. At 66, the method comprises detecting a finger touching one of the additional object icons and then moving in a direction about the pattern of additional object icons (e.g., circular pattern). In response to the detection of the finger movement, the method comprises causing the pattern of additional object icons to animate so as to spin about a center point coinciding with the first object icon.

In some embodiments, the “spin” gesture of FIG. 6 and action 66 in FIG. 9 can be performed without first performing the object icon selection gesture depicted in FIGS. 3A-5. That is, however a group of related object icons are caused to be shown on display 20, the group of object icons can be made to spin as discussed above.

The above discussion is meant to be illustrative of the principles and various embodiments of the present invention. Numerous variations and modifications will become apparent to those skilled in the art once the above disclosure is fully appreciated. It is intended that the following claims be interpreted to embrace all such variations and modifications.
